Default Hole Type — Round vs. Oval

2.3.1   KEY   setting

The Default Hole Type setting controls which hole type is pre-selected when you start a new spec sheet for a bowler. Spectre Cloud supports two hole type options: Round and Oval. Choosing the right default for your shop saves time and reduces the chance of accidentally drilling the wrong type.

🕳️ Understanding Hole Types

Round Holes

Round holes are the standard hole type used in the majority of drilling layouts. They are drilled using a standard bit at a fixed diameter and are the most common choice for recreational and league bowlers.

  • ✅ Used for most conventional and fingertip drilling styles
  • ✅ Compatible with standard inserts and slugs
  • ✅ Faster to drill and fit for most customers

Oval Holes

Oval holes are an elongated hole type used when extra grip surface, a specific release technique, or a custom fit requires it. Spectre Cloud includes a dedicated Oval Calculator to help determine the correct oval dimensions for each bowler.

  • ✅ Provides additional contact area for certain release styles
  • ✅ Often used for bowlers with grip issues or specific fit requirements
  • ✅ Oval dimensions are automatically calculated in the Oval Calculator (Book 05)
  • ❌ Requires additional measurement steps compared to round holes
  • ❌ Not suitable for standard insert sizing

📋 Choosing Your Default

The default hole type is applied automatically each time a new spec sheet is created. You can always override it on an individual spec sheet — this setting simply sets the starting value to match your shop's most common workflow.

Shop Type Recommended Default Reason
General / recreational pro shop Round Most customers receive standard round holes; saves time on every new sheet
Competitive / performance-focused shop Round or Oval Depends on your typical customer base; oval may be more common at high-level shops
Shop specialising in custom fitting Oval If the majority of your drilling work involves oval holes, setting this as default reduces manual selection

🛠️ How to Change the Default Hole Type

  1. Click your Profile name in the top-right corner of the screen.
  2. Navigate to Settings.
  3. Open the Spec Sheet Defaults section (Chapter 2.3).
  4. Locate the Default Hole Type option.
  5. Select either Round or Oval from the dropdown.
  6. Click Save to apply your changes.

📌 Note: Changing the default hole type only affects new spec sheets created after the setting is saved. Existing spec sheets are not modified.

🔄 Overriding the Default Per Spec Sheet

Even after setting a default, you can change the hole type on any individual spec sheet at the time of creation or while editing. The default simply pre-populates the field — it is never locked in.

  • 2.3 — Spec Sheet Defaults (Chapter Overview)
  • 2.3.2 — Default Span Type (F, C, or O)
  • 05 — Oval Calculator (full book dedicated to oval hole measurement)
  • 04 — Spec Sheets (creating and editing spec sheets)

Tip: Not sure which to pick? Start with Round — it's the right default for the vast majority of pro shops. You can always switch to Oval on a per-sheet basis for bowlers who need it, or change the default later as your shop's workflow evolves.
